For our E-Bike tire we fall back on over 100 years‘ experience with moped and motorcycle tires. All of our city/trekking tires are rated to a standard speed of at least 25 km/h.  Those tires marked e50 are also certified for S-Pedelecs. With their high quality structure, puncture protection is high and the  rolling resistance is low offering protection from premature wear brought about by the additional driving force.
